Google Cloud Certified - Professional Cloud Network Engineer Questions and Answers

Question 1

Your organization has Compute Engine instances in us-east1, us-west2, and us-central1. Your organization also has an existing Cloud Interconnect physical connection in the East Coast of the United States with a single VLAN attachment and Cloud Router in us-east1. You need to provide a design with high availability and ensure that if a region goes down, you still have access to all your other Virtual Private Cloud (VPC) subnets. You need to accomplish this in the most cost-effective manner possible. What should you do?

Options:

A.

Configure your VPC routing in regional mode.

Add an additional Cloud Interconnect VLAN attachment in the us-east1 region, and configure a Cloud Router in us-east1.

B.

Configure your VPC routing in global mode.

Add an additional Cloud Interconnect VLAN attachment in the us-east1 region, and configure a Cloud Router in us-east1.

C.

Configure your VPC routing in global mode.

Add an additional Cloud Interconnect VLAN attachment in the us-west2 region, and configure a Cloud Router in us-west2.

D.

Configure your VPC routing in regional mode.

Add additional Cloud Interconnect VLAN attachments in the us-west2 and us-central1 regions, and configure Cloud Routers in us-west2 and us-central1.

Question 2

You are designing a hub-and-spoke network architecture for your company’s cloud-based environment. You need to make sure that all spokes are peered with the hub. The spokes must use the hub's virtual appliance for internet access.

The virtual appliance is configured in high-availability mode with two instances using an internal load balancer with IP address 10.0.0.5. What should you do?

Options:

A.

Create a default route in the hub VPC that points to IP address 10.0.0.5.

Delete the default internet gateway route in the hub VPC, and create a new higher-priority route that is tagged only to the appliances with a next hop of the default internet gateway.

Export the custom routes in the hub.

Import the custom routes in the spokes.

B.

Create a default route in the hub VPC that points to IP address 10.0.0.5.

Delete the default internet gateway route in the hub VPC, and create a new higher-priority route that is tagged only to the appliances with a next hop of the default internet gateway.

Export the custom routes in the hub. Import the custom routes in the spokes.

Delete the default internet gateway route of the spokes.

C.

Create two default routes in the hub VPC that point to the next hop instances of the virtual appliances.

Delete the default internet gateway route in the hub VPC, and create a new higher-priority route that is tagged only to the appliances with a next hop of the default internet gateway.

Export the custom routes in the hub. Import the custom routes in the spokes.

D.

Create a default route in the hub VPC that points to IP address 10.0.0.5.

Delete the default internet gateway route in the hub VPC, and create a new higher-priority route that is tagged only to the appliances with a next hop of the default internet gateway.

Create a new route in the spoke VPC that points to IP address 10.0.0.5.

Question 3

You are troubleshooting an application in your organization's Google Cloud network that is not functioning as expected. You suspect that packets are getting lost somewhere. The application sends packets intermittently at a low volume from a Compute Engine VM to a destination on your on-premises network through a pair of Cloud Interconnect VLAN attachments. You validated that the Cloud Next Generation Firewall (Cloud NGFW) rules do not have any deny statements blocking egress traffic, and you do not have any explicit allow rules. Following Google-recommended practices, you need to analyze the flow to see if packets are being sent correctly out of the VM to isolate the issue. What should you do?

Options:

A.

Create a packet mirroring policy that is configured with your VM as the source and destined to a collector. Analyze the packet captures.

B.

Enable VPC Flow Logs on the subnet that the VM is deployed in with sample_rate = 1.0, and run a query in Logs Explorer to analyze the packet flow.

C.

Enable Firewall Rules Logging on your firewall rules and review the logs.

D.

Verify the network/attachment/egress_dropped_packet.s_count Cloud Interconnect VLAN attachment metric.
